A crowdsourcing initiative to make archaeological archives and artefacts digitally accessible. Originally an Arts and Humanities Research Council (AHRC) funded project, Micropasts began in 2014 as a collaboration between the British Museum and the UCL Institute of Archaeology. Since then a variety of transcription and photomasking projects have been undertaken in collaboration with a number of learned societies and museums.

Notable projects include transcription of the British Museum's Bronze Age Index; transcription of the Egypt Exploration Society's Amarna Object Cards; transcription of Flinders and Hilda Petrie's diaries; ﻿photomasking of artefacts ﻿for 3D images/prints from the collections of the British Museum, the Petrie Museum, the Mary Rose Trust, and the Palestine Exploration Fund.
